So, we've started selling Mexican Coca-Cola in the store I work in. After some prodding, I got the Coke vendor to put the singles in the coolers in the front of the store, instead of selling singles (hot) off the shelf in the back of the store (with the 2L and cans).

Well, I passed a early-20-something co-worker going to break and she had one of these bottles. She looks at me and asks "How am I supposed to open this?"

I tell her I have a bottle opener in my office, so we stop by my office and I hand her the bottler opener. It's one of those flat, metal ones with curved ends and a magnet on it. Nothing special.
